Steps for Installing a Rain Gutter:

2. Measure the fascia to determine the length of the gutter.
3. Apply gutter sealant to an end cap, then press the cap onto one end of the gutter.
4. Secure the end cap to the gutter with a crimping tool.
5. Use a hacksaw and tin snips to cut the gutter to length.
6. Use a hammer and a cold chisel (or a hole saw) to cut a round hole in the gutter for a downspout outlet.
7. Apply gutter sealant to the flange of the downspout outlet, then screw the outlet to the hole in the gutter.
8. Temporarily screw the gutter to the fascia, positioning it about 2 inches below the chalk line.
9. Install hanging brackets onto the gutter, positioning one in front of each rafter.
10. Raise the gutter to the chalk line and fasten each hanging bracket by screwing through the fascia and into the rafter tail.
11. Set two 2-inch-thick concrete pavers on the ground directly below the downspout outlet.
12. Set a rain barrel on top of the concrete pavers.
13. Use a hacksaw to cut and assemble the downspout and elbows.
14. Screw the upper end of the downspout to the downspout outlet protruding from the gutter.
15. Fasten the downspout to the house with mounting straps.
